解决方案 #

1. 降级Remote-SSH扩展版本 #

• 打开VS Code扩展面板，找到Remote - SSH扩展
• 点击扩展卡片右下角的齿轮图标，选择Install Another Version
• 选择低于当前版本（比如0.107.0）的版本安装，重启VS Code后尝试连接

2. 清理VS Code Server缓存 #

• 在远程服务器上，删除VS Code Server的缓存目录：

  rm -rf ~/.vscode-server
  

• 本地端清理Remote-SSH缓存：
  • Windows：删除C:\Users\<你的用户名>\.vscode\extensions\ms-vscode-remote.remote-ssh-<版本号>目录，同时删除C:\Users\<你的用户名>\.ssh\vscode-ssh-hosts文件
  • macOS/Linux：删除~/.vscode/extensions/ms-vscode-remote.remote-ssh-<版本号>目录和~/.ssh/vscode-ssh-hosts文件
• 重启VS Code后重新发起SSH连接

3. 回退VS Code版本到1.85.x #

• 下载VS Code 1.85.x版本安装包，卸载当前1.86.0版本后安装旧版本，再尝试使用Remote-SSH扩展

4. 检查SSH配置与权限 #

• 确认本地~/.ssh/config（Windows为C:\Users\<你的用户名>\.ssh\config）中的远程主机配置正确，端口、用户名、地址无误
• 远程服务器上检查~/.vscode-server目录权限，确保当前用户有读写权限：

  chown -R $USER:$USER ~/.vscode-server
